Revolutionising Visual Learning and Remote Collaboration

In recent years, 3D modelling and photogrammetry have opened remarkable new possibilities for education, research, and collaboration across disciplines. These technologies produce highly accurate, interactive digital representations of physical objects, spaces, and environments. This allows learners and professionals to explore, manipulate, and engage with complex content in ways that were once impossible or highly impractical.

Across the UK, educational institutions have embraced 3D assets and photogrammetric models to transform visual learning. These digital tools enhance student engagement, improve knowledge retention, and significantly widen access to learning materials. Their impact is particularly profound in fields such as medicine, archaeology, engineering, and cultural heritage, where detailed visualisation and interaction are essential for mastering subject matter.

Understanding 3D Modelling and Photogrammetry

3D Modelling involves creating virtual three-dimensional representations of objects or spaces using specialised software. These models may be built from the ground up or developed by processing scanned data. The resulting virtual assets accurately depict shapes, textures, and other physical properties.

Photogrammetry is a method of developing 3D models from a series of high-resolution photographs taken from multiple angles around a real-world object or environment. The process stitches these images together to create models that capture the physical details and surface textures with remarkable fidelity.

Both 3D modelling and photogrammetry output interactive digital assets. These can be rotated, zoomed, annotated, and embedded into immersive learning environments such as virtual or augmented reality, allowing users to engage with content dynamically rather than passively viewing static images or text.

Improving Learning Outcomes Through Interactive 3D

The power of 3D digital assets in education is supported by robust research evidence:

- A 2021 study at the University of Aberdeen, published in the Journal of Anatomy, found that 85% of medical and biomedical students preferred 3D photogrammetry models to traditional 2D images and textbooks. The students reported increased confidence in identifying anatomical structures - an important step towards practical clinical skills.

- A systematic review published in Frontiers in Education in 2020 showed that learners who used interactive 3D models experienced a 75% increase in knowledge retention and a 67% improvement in motivation compared to those using conventional learning materials.

These assets enable students to explore complicated structures repeatedly from multiple perspectives. This repeated spatial exploration supports deeper understanding and improved spatial reasoning - skills that are especially critical in STEM and health science education.

Widening Access and Promoting Inclusivity

Beyond improving comprehension, 3D modelling and photogrammetry play a vital role in making learning more inclusive:

- Digital replicas provide equitable access to physical artefacts or environments that may be inaccessible due to mobility restrictions, sensory impairments, or logistical constraints.

- Universities and colleges can distribute 3D collections digitally to distant learners or partner institutions, broadening participation in distance and blended learning programmes. This model reduces the need for physical handling of fragile or geographically distant specimens, alleviating conservation and transport challenges.

The importance of remote access to quality digital learning materials was sharply highlighted during COVID-19 lockdowns, where many institutions had to pivot quickly to online delivery without compromising educational quality.

Enhancing Remote Collaboration and Multidisciplinary Learning

Embedding 3D models into virtual and augmented reality environments supports powerful new forms of collaboration:

- Learners and researchers can co-examine, annotate, and manipulate digital objects simultaneously, regardless of their physical location. This allows for collective problem-solving and debate in real time.

- Industries such as architecture, engineering, and construction (AEC) routinely use 3D models for project planning, clash detection, and stakeholder engagement. Educational programmes aligned to these sectors increasingly incorporate digital 3D collaboration tools, preparing students for real-world challenges.

Emerging platforms enable immersive, social learning experiences that go beyond traditional lectures, promoting active participation alongside independent study.

Practical Examples Across UK Education

In UK medical schools, photogrammetry provides detailed, reusable anatomy teaching models that complement cadaveric dissection and enhance hands-on sessions with realistic visuals.

Heritage and archaeology courses benefit from digital reconstructions of sites and artefacts, granting students access to locations or fragile items not otherwise available for close study.

Engineering and design disciplines use 3D models to prototype virtually, helping students visualise mechanisms and run iterative modifications before constructing physical models. This reduces costs and speeds experimentation cycles.

How Institutions Can Adopt 3D Modelling and Photogrammetry

For those looking to integrate 3D assets into teaching and research, recommendations include:

- Developing or acquiring high-quality, curriculum-aligned 3D digital resources that meet specific learning goals.

- Training academic staff to effectively embed these technologies within their teaching practice, maximising engagement and educational value.

- Using SCORM-compliant eLearning platforms to deliver interactive 3D content alongside formative assessments and progress tracking.

- Ensuring equitable access to necessary hardware, such as VR or AR headsets, while maintaining alternative access options for all students.

National efforts including the UK Department for Education’s EdTech strategy and associated funding streams offer targeted support to facilitate these innovations.

Conclusion

3D modelling and photogrammetry have evolved into essential components of modern education and collaborative research in the UK. Supported by extensive research, they elevate learning through greater engagement, deeper understanding, and improved inclusivity.

By adopting these tools, UK education providers can create richer, more accessible, and more effective learning environments that prepare students for the demands of a digital and interconnected world.
